Telecommunication

Reliable and flexible DC power solutions for customer premise broadband, low power wireless and other telecommunication applications.

Clear uninterrupted communication is impossible without a clear uninterrupted power supply. Protecting telecommunication lines from disturbances caused by inadequate or unstable power is as important as protecting computer data flow. Perhaps even more so, because power outages often come hand in hand with natural and other disasters, when the ability to quickly summon help is particularly critical. To protect telecommunication lines from power disturbances, APC by Schneider Electric offers the following two solutions: PowerShield, a DC UPS designed for protecting the customer premise equipment of hybrid fiber-coax, fiber to the home (FTTH), and fixed wireless local loop (FWLL) networks. Magnum VS, a modular, rack-mountable DC power plant for low power wireless, customer premise and distributed network applications.

Integral over-current protection devices protect the system against overload faults.

Extendable Run Time

Additional batteries can be added to provide power to the load for an extended period of time in the event of utility supply failure.

Sizing and run time calculators are based on Watt ratings. VA (Volt-Amp) ratings are also a common method for measuring power but provide less accurate results. On APC.COM, VA values are often shown for convienience and may be entered as input data. However, VA values are always translated into Watts. This translation is done using an approximation formula which assumes that low VA loads have a power factor of around 0.6 and high power loads have a power factor of nearly 1.0, which is representative of typical, (but not all) computing equipment. For highest precision, use Watt values where available.

The translator below shows how VA can be converted to Watts using the APC.COM formula:
